Yeah they all have elites as bosses at the end of class quests. Haven't done the Jedi knight yet, but the main difference I've noticed between the smuggler and the consular is at the end there are usually mutiple stronger targets in the Jedi class quest (at least in case of the consular).
Sorry I couldn't go with you to Nar Shadda last night, the end of chapter one and start of chapter two in consular story line took forever. 1 death, but just took time to kill everything. Even had a champion in it that was optional...of course I had to try to kill it. I died with the champ having 1% health...the other NPCs killed her, so no do over there.
